1. A user equipment (UE) in a wireless communication system, comprising:
a transceiver; and
at least one processor coupled to the transceiver, and configured to:
measure a peak-to-average power ratio (PAPR) of a data signal, wherein the data signal includes a modulated data symbol sequence,
determine whether the measured PAPR is greater than a PAPR threshold,
in case that the measured PAPR is greater than the PAPR threshold, select a data transformation index having a smallest PAPR among a plurality of data transformation
indices, wherein the data transformation index indicates at least one scheme of a data transformation,
transmit, to a base station (BS), information related to the selected data transformation index, and
transmit, to the BS, a transformed data signal generated by applying the data transformation corresponding to the selected data transformation index to the data signal.
